Hi John

What are the latency settings? And what is your VST performance window saying when the pops appear?

Best, Alan

Thank you for your response question...

My VST meter shows about 55% load with all my reverence reverbs are on. They real time peak is always bouncing to the max no matter if I have the reverbs on or off. Taking off the Reverence reverbs does clean it up but even when I add just 1 it starts to pop. The weird thing about it is, it didn't start popping until much later after I had added those reverbs. So it wasn't that obvious when trouble shooting but when I finally turned off all VST efx and then slowly added each one back one by one I was able to isolate it down to that specific effect.

My Latency settings are - 5ms on Input and 7ms on output.

Is there a way to increase VST performace? My cpu's are only using about 25% on average with everything on.

Thanks for any help you can give.
